| Description
| - Tepelná stálost dvaceti pěti polynitroarenů byla stanovena ne-izotermickou diferenční termickou analýzou (DTA), a byla vyjádřena jako počátek tepelné dekompozice. Elementární náboje na dusíkových atomech z polynitroarenů byly vypočítán ab initio DFT B3LYP/6-31G** metodou. Vztah byl potvrzený mezi zmíněnými počátky rozkladu a čtverci hodnot nábojů dusíků nitroskupin, které jako první podléhají odštěpení. Ve smyslu tohoto vztahu, se studované substance dělí do pěti skupin. Principu vztahu a důvod této separace jsou diskutované. Stabilizační vliv krystalické mřížky studovaný polynitroarenú může být posouzen pomocí DTA-měření těchto substancí v jejich roztoku v 1,3,5-trinitrobenzenu. (cs)
- Thermal stability of twenty-five polynitro arenes has been examined by means of non-isothermal differential thermal analysis (DTA), and it was expressed as an onset of thermal decomposition, TD. Electronic charges, qN, at nitrogen atoms of the polynitro arene molecules were calculated by means of the ab initio DFT B3LYP/6-31G** method. The relationship was confirmed between the onsets TD and squares of the qN values for the nitro groups that are primarily split off. In the sense of this relationship, the compounds studied fall into five groups. The reason of this diversification and principle of the relationship existence are discussed. It is stated that stabilising influence of the crystal lattice of the studied polynitro arenes can be evaluated by DTA of solutions of these compounds in 1,3,5-trinitrobenzene (TNB).
